In the related art, the inventors of the present invention suck air into a bubble water generator by intake air and mix it with water to form a water stream containing bubbles, and finally generate bubble water. Although there are water generators, research has found that the bubble water generation effect of such bubble water generators is not good. Since the inventors of the present invention cannot control the amount of air intake satisfactorily by such a bubble water generator, excessive intake of air causes the bubbles in the water stream to become large, resulting in high-concentration microbubbles. We have found that it is not formed and leads to a poor user experience.

Based on this, the present invention provides a bubble water generator. The bubble water generator includes a diversion device, a mixer, an intake flow path, and a water discharge surface cover, and the diversion device includes at least one first water inlet hole between the mixer and the diversion device. A first chamber is formed in the mixer, the mixer includes at least one second entry hole and at least one return hole, and the at least one second entry hole is paired with the at least one first entry hole. Corresponding to one, the flow area of each of the second water inlet holes is larger than the flow area of the corresponding first water inlet hole, and the at least one return hole, the at least one first water inlet hole and the at least the at least one. Each of the first water inlet holes communicates with the first chamber, the intake flow path communicates with the first chamber, and a second chamber is formed between the water discharge surface cover and the mixer. The at least one second water inlet hole and the at least one return hole communicate with the second chamber.

The water flow sequentially flows through the first and second inlets, and the circulation area of the second inlet is larger than the circulation area of the first inlet. Therefore, according to Bernoulli's principle, the second inlet has a constant negative impact. When pressure is generated, the air in the outside world passes through the intake flow path and the first chamber in order, and then is sucked into the second water inlet hole to form a mixed water flow including a water flow and a certain bubble, and this mixing is performed. After the water stream has flowed into the second chamber, a portion of the mixed water stream passes through the return hole and returns to the first chamber, then is sucked back into the second entry hole and circulates back and forth in this way. Since the partially recirculated mixed water stream fills the first chamber in the process of reciprocating circulation, it prevents the outside air from being sucked into the bubble water generator and plays a role of reducing the amount of air sucked in. When the mixed water flow is not filled in the first chamber due to a part being sucked into the second water inlet hole again, the suction amount of the outside air is automatically controlled by continuing to suck the outside air. Achieve the effect. At the same time, the amount of air taken in from the outside world is effectively controlled, so that the bubbles in the mixed water stream containing constant bubbles become smaller, so that the bubble water generator generates bubble water containing microbubbles. Can be done.

The annular wall portion 520 surrounds the peripheral edge of the second disc portion 510 and projects from the third surface 511 and the fourth surface 512, including the surface 511 and the fourth surface 512. After the shunt 30 and the mixer 50 are assembled, the central axis L defined by the first disc portion 310 overlaps with the central axis L defined by the second disc portion 510.

The mixer 50 includes a plurality of second water inlet holes 513 and a plurality of reflux holes 514, the plurality of second water inlet holes 513 are formed in the second disk portion 510, and the third surface 511 and the fourth surface 512 are formed.

Therefore, according to Bernoulli's principle, the second inlet hole When a constant negative pressure is generated in 513, the air in the outside world passes through the intake flow path 314 and the first chamber 60 in order, and then is sucked into the second entry hole 513 to include a water flow and a constant bubble. After forming a mixed water stream and the mixed water flow flowing into the second chamber 80, a part of the mixed water flow passes through the return hole 514 and returns to the first chamber 60, and then is sucked into the second water entry hole 513 again. It circulates back and forth in this way. Since the partially recirculated mixed water flow fills the first chamber 60 in the process of reciprocating circulation, it prevents the outside air from being sucked into the bubble water generator and plays a role of reducing the amount of air sucked, and this mixed water flow If the first chamber 60 is not filled with the mixed water flow as a part of the water is sucked into the second water inlet 513 again, the amount of the outside air sucked is automatically increased by continuing to suck the outside air.
